Embodiment is applicable to Any user device (such as user terminal, via node, server, node, corresponding assembly) and/or is applicable to any communication system or any combination of the different communication systems of support required function.Communication system can be wireless communication system or utilize fixed network and the two communication system of wireless network.The standard fast development of employed agreement, communication system, equipment (such as server and user terminal, especially in radio communication).This development may need the extra change to embodiment.Therefore, all words and express and should widely be explained, and these words and expression are intended to signal and unrestricted embodiment.
Below, to use based on senior LTE(LTE-A) the radio access architecture as embodiment applicable to the example of access architecture different exemplary embodiments are described, senior LTE in down link based on orthogonal frequency division multiplexing multiple access (OFDMA) and in up link based on single-carrier frequency division multiple access (SC-FDMA), yet embodiment is not limited to this framework.It will be apparent to those skilled in the art that can also be by suitably adjusting parameter and process, the communication network that embodiment is applicable to have the other types of appropriate device.For example, embodiment can be applicable to Frequency Division Duplexing (FDD) (FDD) and time division duplex (TDD) the two.
In OFDM (OFDM) system, usable spectrum is divided into a plurality of orthogonal sub-carriers.In ofdm system, available bandwidth is divided into narrower subcarrier, and in parallel flow, transmits data.Each OFDM symbol is the linear combination of the signal in the subcarrier each.In addition, before each OFDM symbol Cyclic Prefix (CP) is arranged, this Cyclic Prefix is used to reduce intersymbol interference.Be unlike among the OFDM, the SC-FDMA subcarrier is not modulated independently.
Typically, (e) NodeB(" e " represents senior evolution) need know the channel quality of each user's set and/or compare the preferred pre-coding matrix of subband (and/or the special-purpose feedback information of other multiple-input and multiple-outputs (MIMO) that is distributed, such as channel quantitative), with the transmission of scheduling to user's set.Usually give (e) NodeB with required information signaling.
Figure 1A and 1B have described the example of simplified system architecture, and it only shows some elements and functional entity, and all these elements and functional entity all are logical blocks, and its realization can be different with shown realization.Figure 1A is that logic connects with being connected shown in the 1B; Actual physics connects can be different.It will be apparent to those skilled in the art that typically system also comprises except that the function shown in Figure 1A and the 1B and other functions and structure the structure.
Yet embodiment is not subject to the system that provides as example, but other communication systems that those skilled in the art can make solution be applicable to is provided with necessary attribute.Some examples that are used for other options of appropriate system are Universal Mobile Telecommunications System (UMTS) radio access network (UTRAN or E-UTRAN), Long Term Evolution (LTE, identical with E-UTRA), WLAN (wireless local area network) (WLAN or WiFi), World Interoperability for Microwave Access, WiMax (WiMAX), Bluetooth (bluetooth), personal communication service (PCS), Wideband Code Division Multiple Access (WCDMA) (WCDMA) and the system that uses ultra broadband (UWB) technology.
Figure 1A shows E-UTRA, LTE or senior LTE(LTE-A) the part of radio access network.E-UTRA is the air interface (the UTRA=UMTS terrestrial radio inserts, the UMTS=Universal Mobile Telecommunications System) of version 8.LTE(or E-UTRA) more obtainable advantages are to use the possibility of plug-and-play apparatus and Frequency Division Duplexing (FDD) (FDD) and time division duplex (FDD) in same platform.
Figure 1A shows user's set 100 and 102, and it is configured on one or more communication channels 104,106 in the sub-district and provides (e) NodeB 108 of this sub-district to carry out wireless connections.Physical link from user's set to (e) NodeB is called as up link or reverse link, and the physical link from NodeB to user's set is called as down link or forward link.
Senior enode b among NodeB or the senior LTE (eNodeB, eNB) is the calculation element that is configured to control the radio resource of its communication system that is coupled to.(e) NodeB can also be known as base station, access point or comprise the docking facilities of any other type of the relay station that can operate in wireless environment.
For example, (e) NodeB comprises transceiver.From the transceiver of (e) NodeB, be provided to the connection of antenna element, this antenna element and user's set are set up bi-directional radio relay link.This antenna element can comprise a plurality of antennas or antenna element.(e) NodeB further is connected to core net 110(CN).According to this system, the peer device on the CN side can be service system architecture evolution (SAE) gateway (route and transmit user data packets), be used to provide internuncial grouped data network gateway (PDN GW) of user's set (UE) and external packet data network or mobile management entity (MME) etc.
Typically, communication system comprises more than (e) NodeB, and in this case, (e) NodeB can also be configured to come and communicate with one another by the link (typically, radio link) that designs for this purpose.These links can be used for the signaling purpose.
Communication system can also communicate with other networks (such as public switch telephone network or the Internet 112).
User's set (being also referred to as UE, subscriber equipment, user terminal etc.) has been illustrated one type the equipment that the resource on the air interface is assigned with and is assigned to, and therefore, can utilize corresponding equipment (such as via node) to realize having described herein any feature of user's set.The example of this via node is layer 3 relaying (from the backhaul relaying) towards the base station.
Typically, user's set refers to the portable computing that comprises with subscriber identity module (SIM) or the wireless mobile communication device do not operated with SIM, and it includes but not limited to the device of following type: travelling carriage (mobile phone), smart phone, PDA(Personal Digital Assistant), mobile phone, laptop computer, game console, notebook and multimedia device.User's set (layer 3 via node) perhaps in certain embodiments, is configured to carry out one or more in the user device function.User's set can also be called as subscriber unit, travelling carriage, remote terminal, accesses terminal, user terminal or subscriber equipment (UE), only mentions several titles or equipment.
Should be appreciated that in Figure 1A for clear, user's set is depicted as and comprises only 2 antennas.The number of reception and/or transmitting antenna can change naturally according to current execution mode.
In addition, although equipment has been depicted as single entity, can realize different units, processor and/or memory cell (all not shown in Figure 1A).It will be apparent to those skilled in the art that, the system of being described only is the example of the part of radio access system, and in fact, system can comprise a plurality of (e) NodeB, user's set can have the access to a plurality of radio plots, and system can also comprise other equipment, such as physical layer trunking node or other network elements etc.Among NodeB or the eNodeB at least one can be the nodeB of family (e).Additionally, in the geographic area of radio communications system, can provide radio plot and a plurality of radio plot of number of different types.Radio plot can be to have the nearly macrocell (or umbrella sub-district) or the littler sub-district such as Microcell, Femto cell or picocell of the big sub-district of conduct of the diameter of tens kms usually.(e) NodeB 108 of Fig. 1 can provide these sub-districts of any kind.Cellular radio system may be implemented as the multitiered network that comprises polytype sub-district.Typically, in multitiered network, a Node B provides one or more sub-districts of one type, and therefore, needs a plurality of Node B that this network configuration is provided.
The modern multimedia device makes it possible to provide more services to the user.The use of multimedia service has increased the demand that rapid data is transmitted, this so that need investment in the radio net.Typically, when using modern service and using, realize that the network of being developed of enough user experiences means higher installation and operating cost (OPEX).In addition, because the power consumption of base station typically maps directly in the operating cost (OPEX) of Virtual network operator, realize that therefore the technology of reduction of the energy consumption of network has been the focus of being paid close attention to.
A kind of means of using when improving the use of Internet resources in cost-efficient mode are to introduce remote radio frequency (RF) head and base station machine room (hotel): the base station is split into two parts: remote RF head and the base band radio server by wire link (Radio Link also is possible) coupling typically.This has produced following system, and wherein, the base band radio server can be deployed in easy access and/or low-cost position, and remote RF head (RRH) can be installed in the approaching roof of antenna on.Usually, the remote RF head holds radio-related functions (transmitter RF, receiver RF, filtering etc.), and base station portion is carried out other base station functions.Each wireless dateline can produce the sub-district of control discretely, but these sub-districts can also constitute the cell cluster with spaced antenna.
In addition, a plurality of base band radio server can be placed on the same position place, utilize same asset, be connected with backhaul such as power supply, and the RF head can be distributed on the position that the covering of expectation radio is provided.This design is initiated the support of (OBSAI) standard by open base station architecture.The design of a plurality of remote RF heads that are coupled with centralized base station can be known as base station (BTS) machine room.Having extensively, integrated and base station machine room Combined Treatment also is known as cloud RAN(C-RAN).An advantage of BTS machine room framework is that it provides the ability of cost-benefit BTS redundancy.
Figure 1B shows the example that can how to realize the design of BTS machine room in the system of Figure 1A.Similar reference marker refers to similar units, element, connection etc.Difference between Figure 1A and the 1B only is described in this context.
This paper only conceives as example with the BTS machine room.Yet embodiment is not subject to this design.For example, embodiment is applicable to network, and wherein, node and optical fiber are coupled.
In Figure 1B, wireless dateline 114 is placed near the antenna 116, and base station 110(in this example, and remainder eNodeB) is positioned at the centralized location place that can be suitable for a plurality of base stations.In this example, utilize optical fiber to connect 120 links of realizing between wireless dateline 114 and the base station 110.Below, some embodiment are disclosed in further detail about Fig. 2.Embodiment is particularly suited for being carried out by the centralized network controller that can be arranged in node apparatus, main frame or server, and perhaps, node apparatus, main frame or server can be coupled to this centralized network controller.
The embodiment of Fig. 2 usually base station, node, main frame, server etc. of the function required with being provided with execution base station and/or radio network controller function is relevant.Under the situation of using the design of BTS machine room, can get rid of radio function.This embodiment starts from the frame 200.This embodiment realizes at least in comprising the communication network of two operation layers.
Typically, operation layer means the emission/receiving layer that is used for network operation of Virtual network operator.
In one embodiment, one or more " cover layers " that can be regarded as being designed to provide covering in the operation layer, and (one or more) other layers can provide " capacity ".
Operation layer covers substantially the same at least geographic area, and therefore, typically, operation layer is corresponding with frequency carrier.
Should be noted that operation layer goes for the layer of same radio access technology (RAT) and the layer (for example, WCDMA/HSPA and LTE) of different RAT.
In frame 202, monitor the service condition of these at least two operation layers.
The overall load situation of the information relevant in can be Network Based with service condition.Can collect this information in many ways, example is that the node in the selected zone obtains and user's the number or the relevant information of utilance of data transfer resource.
If the service condition indicating services reduces first predetermined condition, usually mean that it enough influences the utilization of catabiotic resource (frame 204) significantly, then so that at least one mode that is cleared in these at least two operation layers, at least one from these at least two operation layers of business is sent at least one other operation layer (frame 206) in these at least two operation layers.
Whether the business of can assessing in many ways reduces, and the business of first predetermined condition reduces degree.Option is a threshold value of using the lower limit to traffic density to define before taking to move.This threshold value can be used as an operational network parameter and pre-determines.Can also adjust this threshold value according to traffic forecast or the statistical information relevant with the typical services state on the same day in a different time of one day or a week.Typically, this threshold value compromise based between the ability of supplying with enough capacity and the saving that realizes in the energy consumption, and so depend on the needs and the hope of operator.
In order further to make professional transmission clear, provide the example of simplification.In this example, at least one layer that empty is called as " cover layer ", and the professional layer of reception is called as " capacity layer ".Typically, " cover layer " provides the layer of best intrinsic covering, and for example, it can be the lowest possible frequency carrier wave in the network of operator.
Empty " cover layer " by business being transferred at least one capacity layer node.This is can be by the business guiding action of using various means to realize.Cover layer is cleared, under the situation that the releasing activity user does not connect this layer is reconfigured.Should recognize, empty and totally or to depend in part on current wireless electricity covering needs.The zone that empties can cover the whole overlay area of whole BTS machine room overlay area, wireless dateline or its part or the like.
Can switch to the preferred layer of network institute and come transport service by making user's set carry out " normally ", perhaps switch and to initiate by network, and therefore, force user's set to switch.
When user's set detects radio bearer setup complete usually and switches, can switch by turn-offing node " propelling movement ".Handoff parameter can be set, select preferred capacity layer with " forcing " user's set.Should recognize that typically, not all operation layer all is cleared, to guarantee regional service covering to the user.Can maximize attainable energy saving by the number that maximizes the layer that will empty, thereby the upper limit is a layer that is not cleared.
In frame 208, provide purpose to reconfigure this at least one other operation layer for service.The operation layer that serves as receiving layer is redeployed as and makes it be adjusted to can to provide service according to current demand.Reconfigure and to comprise the zone that each wireless dateline of definition is served and/or carry out new cooperative operation layer.In the cooperative operation layer, node can be changed into the diversity node that is used to keep the radio covering.Also node can be back to " normally " operator scheme from diversity mode.In frame 210, turn-off the radio function node of serving the operation layer after emptying, to reduce energy consumption.Can carry out this switching by turn-offing the wireless dateline that produces the radio covering.Under the situation that node apparatus is not separated by the remainder with wireless dateline and base station functions, turn-off the radio function node and may mean the radio function that turn-offs node apparatus.
In this example, when all business are moved into " capacity layer " radio function node, " cover layer " radio function node can change operator scheme: can be at the bigger cell size of " cover layer " definition, and " cover layer " node remains on activity in the bigger covering so that turn-off some radio function nodes and more only make.Because interference is lower, these less websites still can provide the covering on the Zone Full, although the population size of network reduces now.Should be appreciated that this reconfigures can also be implemented as step-by-step procedure, and wherein, some zones were converted into covering " island " before other zones.In this case, " cover layer " radio function node that will be converted into single covering " island " is handled as group.
Can be if having the operation layer of bigger cell size in response to most of at least service needed, then empty the operation layer of primary reception by business being transmitted back to the operation layer that has bigger cell size now at least in part to the business that is transmitted, and, turn-off the radio function node (now unwanted those radio function nodes) of primary reception to the operation layer of the business that is transmitted.In other words, under the situation that all business can be handled by " cover layer " that have bigger sub-district now, surplus lines on current being in " capacity layer " can be sent to " cover layer " (perhaps its at least a portion), and can turn-off idle capacity radio function node, to obtain the further saving in the energy consumption.According to current capacity needs, in the radio function node some can be remained in on-state.
If there are the needs to the complementary network capacity, then capacity radio function node can still be in the operation.For example, at least some in the capacity radio function node can be served as the diversity node.
When " normally " state is got back in the business increase, network can be back to normal manipulation mode, that is, business can be transmitted back to " capacity layer " from " cover layer " expanded, " cover layer " can be reconfigured in the sub-district of low capacity more, and business is carried out balance.In this context, the capacity node that serves as the diversity node can also be back to " normally " mode of operation.
Should recognize, can in diversity mode, cooperate and operate and further expand the overlay area of coverage cell more than the element (antenna) of a sub-district by order, thereby reach from network perspective even more energy saving.This solution can be feasible concerning the network with low-down service condition.
If the service condition indicating services increases second predetermined condition (frame 212), then dispose at least one new operation layer and/or reconfigure in these at least two operation layers at least one, with increase capacity (frame 214).
Can assess satisfying of second predetermined condition in many ways.Option is a threshold value of using the upper limit to traffic density and/or service ability to define before taking to move.This threshold value can be used as an operational network parameter and pre-determines.Can also adjust this threshold value according to traffic forecast or the statistical information relevant with the typical services state on the same day in a different time of one day or a week.Typically, this threshold value depends on the needs and the hope of operator.
If current network can not provide sufficient service, then can create one or more new operation layers.If used BTS machine room design, then can maybe will serve the wireless dateline in another zone and be directed to the hot spot region and make " old " and " newly " of serving this zone wireless dateline execution cooperative operation layer create new operation layer by for example connecting multi radio head more.In the cooperative operation layer, node can be changed into the diversity node that is used to keep the radio covering.Also node can be back to " normally " operator scheme from diversity mode.Can also reconfigure operation layer by for example adjusting cell size (multicapacity more if desired, then typically make sub-district littler).
The option that existing " maximum " grid of power amplifier and/or antenna is fitted to the user distribution of current existence in the network also is provided.Sometimes need all these power amplifiers and/or antenna, but usually, the life period section, covering so/or diversity mode in only need minority in them.Because centralized controller is recognized instantaneous business in the whole network usually, so its varying load system can be fitted to the time.Typically, as to user's the current distribution and/or the response of the load on the network, initiate the adaptive of operation layer.
Operation layer can be fitted to another link adaptation at interval at interval from a link adaptation, for example be fitted to another TTI from a Transmission Time Interval (TTI), as long as for the power amplifier and/or the antenna that are under revising, the user does not need resource to get final product.Otherwise before adaptive, the user must disconnect the resource of being discussed, and in this case, reconfigures and depends on release mode etc.Typically, TTI is corresponding to the time remaining time of 1 ms.Adaptive can be called as fast or even instantaneous of therefore, in a TTI, carrying out.
More than Shuo Ming embodiment provides realizing fast and simply link adaptation.These embodiment utilize network node as the fast reaction entity by centralized network controller (such as, the CPU that can carry out synchronously and coordinate operation by network) control.Utilize this centralized control, can have the dynamic operation to selected layer, make operation layer can comprise a node, perhaps a plurality of nodes can be cooperated with establishment cooperative operation layer, and the operation layer configuration can be fitted to current needs.
The centralized network controller can be arranged in node, main frame or server, perhaps this centralized physical controller can be placed in the identical house or near, and can be coupled to the node that base station and/or network control function are provided.This embodiment ends in the frame 216.Can repeat this embodiment in many ways.An example is illustrated by the arrow among Fig. 2 218.
More than steps/points, signaling message and the correlation function in Fig. 2, described not according to the absolute time order, and side by side or by the order execution in step different with giving definite sequence/in some.Can also carry out other functions between the steps/points or within steps/points, and can between the message of being illustrated, send other signaling messages.The part of some in the steps/points or steps/points can also be left in the basket or be replaced by the part of corresponding steps/points or steps/points.An example of possible change is: in an embodiment, can monitor and may professionally increase before may professionally reduce.
Should be appreciated that herein, emission and/or receive may mean by situation ground prepare emission and/or receive, prepare message or the physical transmit that will launch and/or receive and/or receive self etc.
Embodiment provides following equipment: this equipment can be any node, main frame, server or any other suitable equipment that can carry out the above process of describing about Fig. 2.Fig. 3 has illustrated to be particularly suited for the simplified block diagram according to the equipment of embodiment operated as node, main frame or server.This equipment is suitable for controlling the wireless dateline that produces radio plot.This equipment can comprise the centralized network controller that can be arranged in node, main frame or server or be coupled with it, perhaps is arranged in this centralized network controller.
